Question

Answer 1

You can get the ticks and format it like you want.

plt.plot(np.arange(1, 10), np.arange(1, 10)**5)
ax = plt.gca()
plt.ticklabel_format(axis='y', style='sci')
ax.yaxis.major.formatter.set_powerlimits((0,0))

xx, locs = plt.xticks()
ll = ['%.1f' % a for a in xx]
plt.xticks(xx, ll)
plt.show()
